22.4.10 Determining What Is Instrumented

It is always possible to determine what instruments the
Performance Schema includes by checking the
setup_instruments table. For
example, to see what file-related events are instrumented for
the InnoDB storage engine, use this query:

An exhaustive description of precisely what is instrumented is
not given in this documentation, for several reasons:

What is instrumented is the server code. Changes to this
code occur often, which also affects the set of instruments.

It is not practical to list all the instruments because
there are hundreds of them.

As described earlier, it is possible to find out by querying
the setup_instruments table.
This information is always up to date for your version of
MySQL, also includes instrumentation for instrumented
plugins you might have installed that are not part of the
core server, and can be used by automated tools.
